Maintenance of rail clamp plates

In order to prolong the service life of our rail clamp plates, we need to maintain them to make them have a longer service life. In the process of using the welding rail clamp plates, they will inevitably suffer some bumps and wear. By using some skills to maintain the welding rail clamp plates, the service life of the welding pressure plate will be longer. Thereby improving economic efficiency.
1. After removing the welding pressure plate, use a steel brush to brush off the rust, and then use dilute hydrochloric acid (concentration of 15% to 20%) to remove the rust spots, so that the welding pressure plate shows the metallic color.
2. If the welding seam of the plug is cracked due to planning, it needs to be repaired. That is, after the double-sided planing, each welding platen is subjected to a steam pressure test one by one, and if any water droplets are found, make a mark. After turning off the test steam, use an angle grinder to grind out a long groove or around groove at the welding seam emerging from the water polo, and then surfacing, and then smooth it with a grinder.
In addition to relying on good quality, the utility of the rail pressing plate also needs to strictly follow the steps in the installation. After laying the composite rubber backing plate on the rail joint, adjust the positioning of the rail, and install the bolts, pressing plate, and other parts in a complete manner. Flange, and then install the backing plate, spring washer, and other components, the allowable error should be controlled within 5 mm when the track is installed.

What are railway rail fasteners？

What are railway rail fasteners？ Railway rail fasteners Railway rail fasteners are a kind of railway accessories. The parts used to combine rails and sleepers (or other types of under-rail foundations) on the track are also called central joint parts. Its function is to fix the steel rail on the sleeper, maintain the gauge and prevent the longitudinal and lateral movement of the rail relative to the sleeper. The railway rail fastener system is divided into the shrapnel fastener system, gusset fastener system, and elastic strip fastener system. The gusset-type fastener is composed of a gusset plate, a threaded spike, a spring washer, an iron seat, and a buffer pad. The threaded spike is anchored in the reserved hole of the concrete sleeper bearing platform with sulfur cement mortar, and then bolts are used to fasten the buckle. Plate fastened. There are elastic strips I, II, and III types of clip fasteners. Type I elastic strip is composed of ω elastic strip,  screw spike , gauge b...
